CHESTER E. HENNING, OF RUDOLPH, OHIO.

GAS-ENGINE STARTER.

To all whom it may concern:

Be it known that I, CHESTER E. HENNING, a citizen of the United States,residing at Rudolph, in the county of Wood and State of Ohio, haveinvented certain new and useful Improvements in Gas-Engine Starters; andI do hereby declare the following to be a full, clear, and exactdescription ot the invention, such as will enable others skilled in theart to which it appertams to make and use the same.

This invention has reference to gas engine igniters or starters and isespecially adapted for use upon stationary gas engines.

The object of the invention is to provide a simple and inexpensiveappliance adapted to be screwed into the cylinder head or wall of theadmission chamber, connecting with the cylinder, and by means of whichthe charge in the cylinder may be ignited by the application of alighted match.

To this end the invention embodies the novel combination, arrangementand details of construction hereinafter shown, described and claimed.

In the accompanying drawings illustrative of my invention, Figure l isan elevation of the igniter showing the same attached; Fig. 2 is alongitudinal section of the same.

Referring to the details, 1 is the body of the igniter having the hollowcenter 2 and the passage 3 connecting with the hollow interior. The body1 has a tapered screwthreaded end 4 to connect the igniter with theengine cylinder head or wall of the admission chamber, shown at 5.

6 is a valve seated at the inner end 7 of the igniter, the valve beingat the inner end of the stem 8 guided for longitudinal movement at 9 inthe body of the igniter. Upon the outer end of the valve stem 8 is acrossarm 10 adjustable along a threaded portion 11 of the stem, a nut 12holding the cross-arm in adjusted position, and 13, 13, are pivotedcatches upon the cross-arm, a spring 14 pressing the outer ends of thecatches apart, the inner ends 15 of the catches being pressed against aslightly tapered and reduced portion 16 of the igniter body when in theposition in dotted Specification of Letters Patent.

lines a, Fig. 2, the catches engaging the shouldered end of the reducedportion 16 when the valve is closed.

Thus in operation, the igniter being screwed into a threaded hole boredinto the cylinder head or wall of the admission chamber, it will be seenthat the valve 6 will be disposed within the cylinder or admissionchamber. The spring catches at the outer end of the valve stem aremanually operated by pressing them together to disengage them from theshouldered end of the igniter body, and the valve is pushed back toassume the position 0, Fig. 2, the inner ends of the catches being inspring pressed contact with the tapered reduced portion of the igniterbody. A charge of mixed gas and air being drawn into the enginecylinder, a match is ignited and applied to the passage 3, the mixturewithin the cylinder being thus exploded. The instant the explosion inthe cylinder takes place, the valve 6 will close automatically, and byreason of the spring catches at the outer end of the valve stem engagingthe shouldered end of the igniter body, the valve will be efiectivelylocked in closed position. When the succeeding charge is drawn into thecylinder the valve being locked will remain seated.

Thus it will be seen that the device is simple, inexpensive andeffective for the purpose of starting a gas engine, especially those oflarge power.

What I claim is 1. In a gas engine starter, the combination with thecylinder or admission chamber, of a body having a passage connecting theinterior of the cylinder or admission chamber with the outer air, areduced portion upon said body having a shouldered end, a valve carriedupon a stem slidably mounted in the body, the valve adapted to seat bypressure within the cylinder or admission chamber to close the passage,and a catch carried at the outer end of the valve stem adapted to slidealong the reduced portion of said body and engage the shouldered end ofsaid reduced portion, substantially as described.
